| abstract | 1,148,893. Carbon electrodes. ALLM€NNA SVENSKA ELEKTRISKA A.B. 20 June, 1966 [21 June, 1965], No. 27359/66. Heading C1A. [Also in Divisions C7 and H1] A porous electrode is formed either by impregnating the pores of a porous conducting material such as carbon with a boron compound or by sintering a powder mixture of the conducting material and the boron compound, the boron compound being at least one of the group: a metal borate, a partially hydrolysed or partially reduced metal borate, a boron oxide or partially hydrolysed boron oxide. The conducting material carbon or a metal (see Division C7) has a particle size of 1 to 100 microns and forms 50-99À5% by weight of the electrode and the borate may be at least one of the borates of Fe, Ni, Co, Cr, Mn, Ag, W, Mo, Na, K with a particle size of 0À001 to 50 microns and forming 0À5 to 50% by weight. The powder mixture may also contain a P.T.F.E. dispersion or up to 25% of ammonium carbonate or bicarbonate and is sintered in vacuo or N 2 at 300-1200‹ C. In the alternative embodiment the sintered conducting material is impregnated with the boron compound or with solutions which form the boron compound in situ. Examples are given of the production of nickel borate by reaction between NiCl 2 and Na 2 B 4 O 7 and NiSO 4 and Na 2 B 4 O 7 ; chromium borate by reaction between CrCl 3 and Na 2 B 4 O 7 ; cobalt borate by reaction between CoSO 4 and K 3 B 3 O 6 ; iron borate by reaction between FeCl 2 and Na 2 B 4 O 7 ; silver borate by reaction between AgNO 3 and Na 2 B 4 O 7 ; and a mixed nickel chromium borate by reaction between NiCl 2 , CrCl 3 and Na 2 B 4 O 7 . |
